Ultimate Archmage Lune Build

Learn how to use one of the strongest characters in Expedition 33 with the Lune Archmage build. Our guide on Lune will show you the best recommendations for weapons, luminas, skills and combos. Drawing from community-shared builds and strategies, we’ve incorporated the latest insights to help you optimize how to play Lune. We hope you enjoy this build on your journey to defeat the Paintress and encourage you to play Lune using the strategies outlined here.

Archmage Lune will have her carrying your team for the entire game and is the perfect character for those who prefer Mage oriented playstyles in games. Through the use of high damage skills and pictos we will make her absolutely one shot all who stand in your way.

Lune Best Attributes

The Best Attributes for Lune are Agility and Vitality.

As a hyper-carry, go all-in on Agility. Not only will it make her much faster but Kralim has S tier scaling so it will boost your damage tremendously. Vitality is the second priority because Kralim scales with it as well. Might is your third priority to boost raw damage. Base attack is a foundational stat that influences Lune’s damage output and interacts with weapon scaling, making it crucial for maximizing her potential.

Use your highest Crit Chance Pictos to raise Crit Chance as high as possible for maximum damage. Critical rate is especially important for maximizing Lune’s damage, particularly when using skills like Elemental Trick and weapons or Pictos that benefit from high crit chances. Agility, Vitality, and Might are your main focus but it’s still important to have high crit chance.

Do not invest points into anything else. Luck can further enhance Lune’s critical hit consistency and elemental skill effectiveness, making it a valuable attribute in late-game builds.

The recommended endgame Attributes for the Archmage Lune Build are:

• Vitality: 99
• Might: 75
• Agility: 99
• Defense: 0
• Luck: 0

Lune’s Stain Mechanic Explained

Lune wields the power of Stains, elemental imprints that allow her to amplify both damaging and healing abilities. Before we dive into the buildcrafting, it’s important to understand how Lune’s Stains work. Each ability she uses creates a stain, and this is how Lune can generate stains throughout combat. You can see which stains each ability creates by looking at the top right of the ability frame.

These stains match the element of the ability, including things like lightning stain, earth damage, or even low single target ice attacks that help set up future combos. For example, using Wildfire creates a Fire Stain. Some abilities, like Wildfire, also generate Light Stains that act as a corresponding stain for any element. Since Light Stains can be treated as this random element, they’re more valuable than the standard Fire, Ice, Electric, or Earth Stains.

Stains empower your other abilities by adding new effects or enhancing damage. Certain combos even deal extreme damage once the right stains are active. Take Wildfire, for example. It needs two Ice Stains to deal increased damage, and when that hit deals damage with the bonus active, it feels completely different. You can get those stains by using an Ice ability, or substitute in Light Stains. So if you have one Ice and one Light Stain, that’s enough to power up Wildfire’s boosted effect for greatly greatly increased damage. Lune also gains a lot of value from setups where critical hits generate additional stain effects, letting her maintain strong uptime on her elemental bonuses.

This means Lune thrives on rotating through all elements. If you’re trying to play her as a pure Fire or Electric mage, you’re playing her wrong because you won’t generate enough stains to power her abilities. At least one lightning ability usually fits into her rotation to keep stain variety consistent.

Lune can also use stains to heal allies, making her a strong support option in addition to her offensive capabilities. One of her early skills, Healing Light, provides healing benefits to the team by consuming stains, which is especially useful in the early to mid-game. She might seem complex at first glance, but once you understand her, she’s incredibly rewarding. As a lune support character, Lune excels at healing and empowering the team, making her a versatile and valuable addition to any party.

Lune Best Skills Explained

Piloting this build will change from early to late game, so first let’s talk about the skills and weapons you will need for the first half of the game. Each battle in the early acts requires adapting Lune’s build and strategy to the specific enemies and challenges you face.

Wildfire

Wildfire is your go-to AoE spell and the first part of your core early-game combo. Wildfire hits all enemies and sets them on fire, doing burn damage over time. This skill deals damage and inflicts the Burn status, which can trigger additional effects with other abilities. Burn damage synergizes really well in this game, especially with Sciel and Maelle, who have fire abilities built into their kits. Increasing burn affinity through certain equipment or skills can further enhance the effectiveness of burn-based skills, maximizing your damage output. You can also use burning shots to apply Burn status and set up combos that amplify damage through status interactions. This spell is incredible, and when combined with Sciel’s setup (which I’ll cover later), it clears out fodder enemies and sets Lune up for her big finisher – Lightning Dance.

Lightning Dance

Lightning Dance is one of Lune’s best spells. The damage in the early portions of the game is simply unmatched. To make it work well, you have to empower it with Fire Stains. Without them, it will feel underwhelming but it’s very easy to build toward. This spell single handedly can one-shot nearly every major boss in Act 2. The reason it’s so strong is because the game’s damage cap in act 1 and 2 is 9999 per hit, Lightning Dance hits multiple times – often hitting the cap 6 times in a row, leading to a total of 59,994 damage which no other ability can achieve with such ease.

Termal Transfer

Thermal Transfer, the second step in our three-part “win the game” combo. I recommend using this instead of Ice Lance just for the early game. AP is hard to come by early, and this skill refunds AP if used on a burning enemy. It occasionally gives you a bonus turn too, which is insanely powerful.

Ice Lance

Ice Lance deals solid single-target damage, generates stains, and slows enemies. If you aim the slow at the right enemy, you can manipulate turn order to let a teammate leapfrog ahead. Turn order is king in this game – if your characters can act before the enemy, then you will not have to worry about dodging, increasing your survival which will in turn increase your damage output. Use this when you feel you have enough AP generation on Lune and no longer need Thermal Transfer.

Elemental Genesis

Elemental Genesis, deals Lightning Dance-level damage but in an AoE. It requires one stain of each element, which makes it harder to obtain, but this build is designed to make that easier. If you’re fighting a group of strong enemies, build toward Genesis. If it’s a single boss, go Lightning Dance. Lightning Dance is much easier to prepare until you get the Kralim weapon.

Crustal Crush

Crustal Crush is our last skill and is great for breaking tougher enemies, which becomes important later on. It also gives you Earth Stains, which the rest of the early build lacks. Crustal Crush can inflict break damage, which is crucial for exploiting enemy weaknesses and interrupting their most dangerous attacks, especially against shielded or high-defense foes.

A powerful skill or effect like crippling tsunami can also be considered for your arsenal, as it can significantly debilitate enemies and turn the tide of a tough battle.

Lune Best Weapons Explained

Lune’s best weapons are Trebuchim, Kralim, and Choralim.

Choosing the right weapon for Lune in Clair Obscur: Expedition 33 is crucial for maximizing her elemental damage and making the most of her stain mechanic. Each weapon offers unique advantages that can dramatically shift your approach to battles, whether you’re aiming for extreme damage with Lightning Dance or setting up devastating combos with Elemental Genesis and Elemental Trick.

Trebuchim

Early in the game, Trebuchim stands out as a top pick. Its ability to generate a random stain with every Free Aim shot means you can quickly build up the stains needed to empower Lune’s core skills. This is especially useful for activating abilities like Earth Rising, Ice Lance, and Immolation, letting you deal medium ice damage or high fire damage even before you have a full arsenal of skills. The random stain generation also helps you adapt to different enemy weaknesses, making Trebuchim a flexible choice for the unpredictable early battles of Expedition 33.

Kralim

As you progress, Kralim becomes a game-changer. This weapon rewards you for rotating through different elements, increasing your damage each time you cast a spell with a new element. If you ever run out of stains, Kralim provides two free stains, ensuring you’re never locked out of your most powerful abilities. The real kicker is its AP recovery: every time you consume a stain, you get 1 AP back, letting you chain together skills like Lightning Dance, Elemental Genesis, and Elemental Trick for extreme damage. Kralim’s synergy with Lune’s kit means you can keep up a relentless assault, always ready to deal ice damage, fire damage, or whatever the situation demands.

Choralim

In the late game, Choralim often takes the crown as Lune’s best weapon. Scaling primarily with Agility and Defense, it rewards investment in these attributes, boosting both your survivability and your offensive power. Choralim’s level 10 passive enhances the effectiveness of Pictos and Luminas that grant multiple turns, while its level 20 passive ramps up your damage output, especially with multi-hit skills like Lightning Dance. This makes it perfect for exploiting the critical hits trigger and unleashing very high fire damage or massive elemental combos. If you’re looking to dominate late-game encounters and push Lune’s build to its limits, Choralim is the weapon to aim for.

Ultimately, the best weapon for Lune depends on your playstyle and the challenges you face in Expedition 33. Whether you prefer the adaptability of random stains from Free Aim shots, the AP efficiency and elemental rotation of Kralim, or the late-game power spikes of Choralim, matching your weapon to Lune’s skills and attributes is key. With the right weapon in hand, you’ll be ready to break through any defense, trigger critical hits, and lead your party to victory in Clair Obscur.

Lune Best Lumina and Pictos

The following Lumina and Pictos are recommended for the Archmage Lune Build in Clair Obscure: Expedition 33.

Early Game

Lune’s early game Lumina and Pictos focus on quick openings that hit hard, consistent tempo boosts, and reliable damage conversion, built around stronger first-turn pressure, bonus energy generation, and exploiting enemy weaknesses for fast momentum.

Late Game

Lune’s late game Lumina and Pictos focus on stacking heavy offensive multipliers, ramping burst damage, and layering on-hit effects, while mixing in key defensive tools that keep her alive during long boss encounters. The overall setup leans into high crit pressure, bonus energy cycling, weakness exploitation, and powerful endgame passives that push her rotation into true late game nuker territory.

How to play the Archmage Lune Build

Early Game ComboYour early combo is simple: Wildfire → Thermal Transfer → Lightning Dance. This sequence will carry you through 95% of early fights, especially if your teammates are pulling their weight. You’ll always start with Wildfire into Thermal Transfer. The final spell depends on the situation—Lightning Dance for bosses, Elemental Genesis for groups of enemies, or even Crustal Crush to prep a break on a meaty enemy to stop them from attacking.

Early Game Weapon

Early game, one of the best choices is Lighterim. It scales with Agility (the best stat in the game), buffs Wildfire’s damage, and reduces its cost. Perfect for your early combo.

Endgame Changes

In Act 3, Lune starts to get outclassed in raw damage by both Verso and Maelle. But she still holds her own, especially with a few tweaks. Thermal Transfer is the first to go. It falls off hard and becomes irrelevant once you have the Cheater lumina, which already gives us extra turns. She’ll have enough AP from luminas and gear that it’s no longer needed.

Officially replace it with Ice Lance if you have not already. It’s stronger in the late game, helps slow dangerous enemies so we can abuse turn order, and still generates useful stains.

Lastly swap out Crustal Crush for Terraquake. Terraquake helps with breaking and still does solid damage while generating Earth Stains. It’s especially good if you pair Lune with Verso or Monoco who are the best breakers in the game.

Late Game Weapon

Endgame, it’s all about Kralim. You can get it before Act 1 ends if you’re very good, but it will be hard. Still, it’s worth the grind – Kralim is Lune’s best weapon for this build and arguably one of the best in the entire game.

It scales with Agility and adds Electricity as an element, which is rarely resisted. Kralim gives three powerful effects:

1. Bonus damage for rotating elements (up to +80%).
2. Generates 2 stains when empty – amazing for lunes opening turns.
3. +1 AP per stain consumed – solves all AP issues.

Combined with Cheater and First Strike, Lune often gets three actions before enemies can move once. This lets her adapt her spell sequence based on the encounter and dominate any battlefield. Kralim alone keeps her competitive with Verso and Maelle well into the endgame. So get to the Yellow Harvest Zone and grab that weapon as soon as possible.

Endgame Combos for Lune

Endgame combo logic stays the same: build toward Lightning Dance or Elemental Genesis, but how you do it changes. With Kralim, you get two random stains when you have none. Because they are random you will either want to start with Terraquake, Wildfire or Ice Lance depending on what stains you need next. Sometimes they’ll both be the same, which can lock you out of Genesis, but it’s worth it – Kralim is one of the best weapons in the game.

Advanced strategies in the late game allow Lune to cast hell repeatedly by optimizing AP management, stains, and pictograms, resulting in massive damage output. The hell skill is especially important for late-game damage, as it can be spammed for devastating results when combined with the right setup. Using the energy master pictogram or skill provides extra AP, enabling powerful combos like casting Hell or Elemental Genesis every turn. Optimizing your rotations and setups with these tools can result in more damage, letting Lune keep up with or surpass other top-tier characters.

Luna Best Team and Companions

The best companions for Lune in Clair Obscure: Expedition 33 are Sciel and Maelle.

Lune is the glue of any composition and works well with anyone but some companions synergize better than others, her favorite partner in crime is Sciel, in the early game if you put Lune first in your turn order to setup wildfire, with Sciel using the ability searing bond as a follow up you can almost instantly win every early engagement through sheer Area of Effect damage. Sciel also comes with the ability to double Lune’s damage via Fortunes Fury, have Lune go instead of Sciel with Intervention, and also refill Lune’s AP through various means, Lune and Sciel are pretty much meant for eachother. As a strong second companion choice Maelle with a fire build is great as well, Lune can also act as a pseudo support for Maelle by starting everything on fire for Maelle to destroy them while Lune acts as a secondary carry without changing your build at all.

Lune and her party members benefit from strong team synergy, maximizing the effectiveness of each character’s skills in battle. Lune’s support role is also crucial, as she can heal, apply debuffs, and provide utility to keep the team alive and flexible in tough encounters.
